8.3. Ventilation function
Ventilation function may be achieved using 2 basic methods:
by employing pneumatic actuators with appropriate installation,
by using an additional electrical actuator powered by 230V~ voltage (drawing below).
For transport reasons, the electrical actuator for ventilation function is usually not factory
installed. It is to be fixed in the upper cross-bar to the existing holes, using ST12-1/8 screws
(For Exxx-230 actuator) or threaded bolts (JMB actuators) supplied with the actuator. It is
recommended to secure the ST12 screws from loosening using Loctite 243, or similar agent.
The actuator has a T-shaped bolt that should be installed in place of the eye bolt. The hook
console should be latched onto the T bolt.
It is recommended to integrate into the system a weather automatics system for controlling
ventilation, e.g. mcrP054; its purpose is to shut any open vents in case of strong wind or
rainfall, protect user property and vent structure from damage.
